5. Customer care and warranty
Two adjacent lit sub pixels:
- Red + Blue = Purple
- Red + Green = Yellow
- Green + Blue = Cyan (Light Blue)
Three adjacent lit sub pixels (one white
pixel).
Note
A red or blue bright dot must be
more than 50 percent brighter than
neighboring dots while a green
bright dot is 30 percent brighter than
neighboring dots.
Black Dot Defects
Black dot defects appear as pixels
or sub pixels that are always dark or
'off'. That is, a dark dot is a sub-pixel
that stands out on the screen when
the SMART All-in-One displays a light
pattern. These are the types of black dot
defects.
Proximity of Pixel Defects
Because pixel and sub pixels defects
of the same type that are near to one
another may be more noticeable,
Philips also specifies tolerances for the
proximity of pixel defects.
Pixel Defect Tolerances
In order to qualify for repair or
replacement due to pixel defects during
the warranty period, a TFT SMART All-
in-One panel in a Philips flat panel
SMART All-in-One must have pixel
or sub pixel defects exceeding the
tolerances listed in the following tables.
